While the standard getRecentPrioritizationFees RPC method provides raw fee data, specialized priority fee APIs from providers like Helius and QuickNode offer more actionable, simplified estimates — including account-specific fee recommendations that account for local fee markets.

Helius Priority Fee API — getPriorityFeeEstimate

The Helius getPriorityFeeEstimate method accepts your serialized transaction (or a list of accounts) and returns a single recommended fee value per priority level. It analyzes recent fee data at the program-account level, giving you a more accurate estimate than global network averages.

The API returns six priority tiers:

• Min: Lowest observed fee in recent slots
• Low (25th percentile): Budget-friendly with reasonable confirmation
• Medium (50th percentile): Reliable for most applications — recommended default
• High (75th percentile): Faster processing during moderate congestion
• VeryHigh (95th percentile): Premium speed for critical operations
• UnsafeMax: Absolute maximum — use only for emergency or MEV scenarios

QuickNode Priority Fee API

QuickNode's Solana Priority Fee API streams real-time mainnet fee data and exposes per-percentile estimates. It integrates with the QuickNode Gas Tracker dashboard and is accessible via their marketplace add-on. The API includes both compute unit price averages and per-transaction fee estimates with percentile distribution.

Chainstack — getRecentPrioritizationFees Integration

For developers using Chainstack RPC nodes, the getRecentPrioritizationFees method can be called directly with a list of account addresses to retrieve localized fee data. This approach is ideal for TypeScript applications that need lightweight, no-dependency fee estimation without subscribing to a specialized API tier.

Choosing the Right API for Your Use Case

• Simple transfers: Use standard RPC getRecentPrioritizationFees — no API key needed
• DeFi / DEX trading: Use Helius getPriorityFeeEstimate with serialized transaction for account-specific accuracy
• NFT minting bots: Use program-specific account filtering to get localized mint fee data
• MEV / arbitrage: Use UnsafeMax tier during competitive windows, then adjust post-event

Rate Limits and Cost Considerations

Priority fee APIs are typically included in standard RPC node plans. Helius, QuickNode, and Chainstack all offer priority fee endpoints on their developer tiers. For high-frequency applications (thousands of transactions per minute), consider caching fee estimates with a 2–5 second TTL rather than fetching per transaction.
